Description

Technical Field

[0001] The utility model belongs to the technical direction of PC exterior walls, and specifically relates to a PC exterior wall installation structure. Background Art

[0002] The PC exterior wall of the existing technology refers to the construction technology that uses precast concrete, referred to as PC components, as the exterior wall. During the installation process, it is often necessary to use hoisting to install it on the corresponding building structure. This is because PC exterior wall components are usually prefabricated in the factory, then transported to the construction site and hoisted to the designated location by crane or other hoisting equipment.

[0003] For example, Chinese patent number CN220768508U discloses an exterior wall PC component, which includes an installation floor, an exterior wall panel is arranged above the installation floor, and a connecting mechanism is provided between the installation floor and the exterior wall panel; a lifting mechanism is provided on the exterior wall panel, U-shaped ribs are provided on the front and rear sides of the exterior wall panel, a baffle is provided on the right side of the exterior wall panel and the installation floor, a fixing mechanism is provided between the baffle and the exterior wall panel, the lifting mechanism includes a lifting rib and a lifting groove, a lifting groove is opened on the top of the exterior wall panel, the lifting groove is located between the connecting grooves, and the same lifting rib is provided between the exterior wall panel and the lifting groove.

[0004] The above technical solution connects the lifting ribs of the lifting mechanism with the corresponding external crane equipment to lift the exterior wall panel, and then through the cooperation of the installation floor, the connecting groove and the connecting ribs, the connecting groove can be easily observed, the connecting ribs and the connecting groove can be quickly plugged into each other, and the exterior wall panel can be quickly installed on the installation floor, saving time and effort and improving work efficiency. However, in actual use, due to the influence of wind and weather or on-site environmental factors during the lifting process, the exterior wall may be bumped during hoisting.

[0023] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides a technical solution: a PC exterior wall installation structure, including a base plate 1 and a prefabricated wall 2, a plurality of snap-fit grooves 3 are opened on the upper side of the base plate 1, a plurality of snap-fit ribs 4 matching the snap-fit grooves 3 are arranged at the bottom of the prefabricated wall 2, two protective frames 5 are installed on the outer side of the prefabricated wall 2, a plurality of U-shaped blocks 6 are fixedly connected to one side of one of the two protective frames 5, and a plurality of plug-in boards 7 matching the U-shaped blocks 6 are fixedly connected to one side of the other of the two protective frames 5.

[0025] Multiple connection ports 8 are provided on the upper sides of the U-shaped block 6 and the plug-in board 7, and fixing pins 9 are inserted into the inner walls of the multiple connection ports 8. The upper sides of the multiple U-shaped blocks 6 are equipped with locking mechanisms 10 that cooperate with the fixing pins 9, and buffer components 11 are installed on the opposite side of the two protective frames 5.

[0026] One aspect of the application of this embodiment is: when in use, first connect it to the external lifting equipment through the lifting rod 17 in the lifting groove 16, and then lift the prefabricated wall 2. When it is close to the ground, the two protective frames 5 that match it can be used to protect multiple corners of the prefabricated wall 2. Then, the plug-in plate 7 is inserted into the interior of the U-shaped block 6, and the fixing pin 9 is inserted into the connecting port 8 to achieve fixation between the U-shaped block 6 and the plug-in plate 7. The protective frame 5 can be made of polyurethane rubber, and its strength can be adjusted by changing the formula. It has a certain ability to absorb and disperse energy. If a collision occurs, the protective frame 5 itself can protect the prefabricated wall 2 to a certain extent, reducing the damage caused by the collision.

[0027] And when there is a collision, the anti-collision plate 112 will first come into contact with the material that is collided. Through the elastic properties of the spring 103 in the damping spring 111, when it is subjected to impact force, its coil or sheet structure will be compressed or stretched. In this process, the spring 103 absorbs part or all of the impact energy, thereby buffering the prefabricated wall 2 again, further reducing the damage to the prefabricated wall 2 caused by collision, thereby achieving the greatest possible protection of the prefabricated wall 2 and improving the protectiveness of the installation mechanism.

[0028] The locking mechanism 10 of this embodiment includes a slot block 101 fixedly connected to the upper side of multiple U-shaped blocks 6, an operating block 102 slidingly fitted on the inner wall of the slot block 101, a spring 103 fixedly connected to one side of the operating block 102 and fixedly connected to the slot block 101, a connecting port 104 opened on one side of the fixing pin 9, and an anti-drop pin 105 fixedly connected to the other side of the operating block 102 and fitted with the connecting port 104.

[0029] Under the action of the spring 103, the operating block 102 is pushed to insert the anti-slip pin 105 into the connecting port 104, so that the fixing pin 9 is limited up and down, and the fixing pin 9 is temporarily fixed. After use, the operating block 102 is forced to bend to make the spring 103 contract, so that the anti-slip pin 105 is separated from the connecting port 104, thereby achieving contact limitation of the fixing pin 9, so that the fixing pin 9 can be separated from the connecting port 8.

[0030] The buffer assembly 11 of this embodiment includes a plurality of damping springs 111 fixedly connected to opposite sides of the two protective frames 5, and two anti-collision plates 112 fixedly connected to one side of the plurality of damping springs 111. When bumped, the anti-collision plates 112 will contact the position where they are bumped, squeezing the damping springs 111, and unloading the force through the damping springs 111. The damping spring 111 is composed of a spring and a damper, which is a prior art and will not be elaborated on.

[0031] In this embodiment, a docking port 12 is provided on the upper side of the plurality of engaging grooves 3. The docking port 12 is arranged in a trumpet shape. By arranging the docking port 12 in a trumpet shape, it is possible to achieve better and faster docking when the engaging rib 4 is installed and docked with the engaging groove 3, by changing from large to small.

[0032] In this embodiment, a guide opening 13 is provided on one side of the multiple operating blocks 102, and a guide rod 14 that cooperates with the guide opening 13 is fixedly connected to one side of the inner wall of the multiple empty slot blocks 101. When the operating block 102 slides, it slides on the guide rod 14 through the guide opening 13, thereby guiding its operating block 102.

[0033] In this embodiment, opposite sides of the two anti-collision plates 112 are fixedly connected with hard rubber 15, and the hard rubber 15 is bonded to the anti-collision plates 112. The hard rubber 15 can cushion the impacted concrete after the anti-collision plates 112 collide with other objects, thereby reducing the degree of damage to the impacted concrete.

[0034] A lifting groove 16 is provided on the upper side of the prefabricated wall 2 of this embodiment, and a plurality of lifting ribs 17 are fixedly connected to the inner wall of the lifting groove 16. The lifting ribs 17 are connected to an external lifting device to realize the lifting operation of the prefabricated wall 2.
